The Gallup poll’s annual “moral acceptability” scale has been conducted since 2001 and charts shifting cultural attitudes on a number of hot-button social issues. In the 2014 list released Friday (May 30), Gallup researchers said 12 of the 19 categories reflected “levels of moral acceptance that are as high or higher than in the past.”

“Americans largely agree about the morality of several issues,” Gallup researchers said. “Most say birth control is acceptable but that extramarital affairs are wrong. However, other issues show clear, substantial divides. These differences are largely explained by party identification, but previous research has shown that age also plays a factor.”

Three issues — sex between an unmarried man and woman, medical research on embryonic stem cells and doctor-assisted suicide — showed a slight increase in acceptability from 2013. Most of the other issues were mostly unchanged.
